Figure 1From: Direct visualization of electroporation-assisted in vivo gene delivery to tumors using intravital microscopy – spatial and time dependent distribution Expression of GFP following electroporation-assisted gene delivery using EP1 GFP expression was monitored in the rat P22 tumor growing in rat dorsal flap window chamber following electroporation-assisted gene delivery using EP1 (8 electric pulses, 600 V/cm, 5 ms, 1 Hz). a. image taken under visible light condition on day 0 (x4 objective), b. image taken under fluorescence epi-illumination on day 0 before administration of DNA and electroporation (x4 objective), c. image taken under fluorescence epi-illumination on day 2 (x4 objective); d. image taken under fluorescence epi-illumination on day 2 (x20 objective).Back to article page
